We place the highest value on the quality of our components. Comprehensive quality assurance is carried out at every stage of production. To this end, we use a wide range of state-of-the-art testing technology. With their help, we can carry out most tests in-house and thus guarantee faster development times and increased data security for our customers. State-of-the-art inspection and test systems enable us to carry out performance tests for all vehicle electrical systems from 12 V to 48 V.

    • Smart-ICT: short-circuit, open-pin and component test
    • Simple function tests
    • Nodel Z Impedance Test (NZT)
    • Electro-Scan Method
    • Optical tests via camera image evaluation

  • Own high-current laboratory with climatic cabinet:

    continuous load tests of DC electronic assemblies with temperature fluctuations: Run-in and burn-in test

The Flying Probe enables simultaneous in-circuit testing (ICT) of the top and bottom of the assembly. With six high-precision probes (needles), 4 of which are on the top side and 2 on the bottom side, the component pins or other contact points on an assembled PCB or assembly are contacted and electrically tested. But also functional tests as well as a combination of functional tests and AOI tests can be easily realized with the Flying Probe.
The electronic components are tested here under thermal load and with regard to load-bearing capacity with respect to the rated current and the short-circuit current. With the available equipment, tests with direct current are possible. Electrical loads of up to 20 kW can be simulated. The equipment of the miunske high-current laboratory enables the performance of:
  • Heating and cold tests according to various standards
  • (heat 80 – 100 °C, cold down to -40 °C)
  • Investigations of direct currents up to 1,000 A
  • Service life tests and continuous switching tests
  • Determination of thermal conductivity
  • Determination of electromagnetic properties by means of power-bound interference pulses
  • Resistance and contact investigation

"Our own high-current laboratory helps us to implement products safely and in compliance with standards from the idea to series production. Almost all the energy we use for component testing is fed back into the power grid. That's how we achieve an efficiency of over 92 per cent."
